Swin Transformer Blocks: To verify the contribution of the Transformer module, the Swin Transformer blocks are replaced by dilated residual dense block (DRDB) proposed by [1]}. As shown in Table REF , the hybrid CNN-Transformer scheme outperforms the pure CNN scheme by about 0.15db and 1.1db in PSNR-\(\mu \)  and PSNR-\(l\) , respectively, and also overtakes in MEF-SSIMd and NIMA. Fig. REF  shows that our method is more realistic in terms of color and details.
